Damien Duff Returns to Premier League as Brentford's Assistant Manager
Damien Duff is back in the Premier League – and back alongside an old ally.
Brentford have confirmed the former Republic of Ireland winger as assistant manager, reuniting him with Keith Andrews after a year out of the game. The 47-year-old has been out of work since stepping down as Shelbourne manager last June, but a series of recent conversations convinced Andrews to bring him into the fold in west London.
For Andrews, fresh from steering Brentford to an impressive ninth-place finish in his first season in charge, this is a key addition to his backroom team rather than a sentimental appointment.
"I've known Damien for a long time," Andrews said. "I’ve seen him up close throughout his coaching journey. We’ve been on courses together and worked together as coaches with the Republic of Ireland national team.
"Damien will bring experience, presence and a real level of detail to our coaching department. He will add to the great group we already have and I’m very pleased that he is joining us."
The two first shared a technical area in April 2020, when Stephen Kenny brought them both into his Ireland coaching staff. Duff’s stint was brief – he left less than six months later – while Andrews stayed on until Kenny’s exit in November 2023 after Ireland failed to reach Euro 2024. The professional respect, though, clearly never faded.
Duff drawn to Brentford’s structure
Duff’s visit to Brentford left a strong impression on him, not least the contrast with some of his former clubs.
"You look at maybe a couple of my ex-clubs, Blackburn and Chelsea, they’re two basket cases and that’s why they are where they are. Brentford, brilliant from top to bottom," he said, underlining his admiration for the way the club is run.
That sense of order and clarity has become Brentford’s calling card in the Premier League era, and Duff arrives with a coaching CV that has steadily grown in depth and responsibility since he hung up his boots.
After a decorated playing career with Blackburn, Chelsea, Newcastle and Fulham, his first steps into coaching came at Shamrock Rovers, where he took charge of the Under-15s in 2017. It was a quiet, deliberate start, far from the spotlight that followed him as a player.
The profile changed when Celtic came calling. Neil Lennon brought Duff to Parkhead in January 2019, and the former winger embraced the chance.
"The next best thing when you finish is obviously coaching and the next best thing for me, I didn't play for Celtic, but to come and coach here is top class," he said at the time.
As first-team coach under Lennon, Duff helped Celtic complete the treble treble and secure a ninth consecutive Scottish Premiership title. He walked away on a high, choosing to focus on his role with Kenny’s Ireland instead. Family reasons, he said, were central to the decision to leave Scotland despite that torrent of success.
Turbulent Ireland spell, rapid rise with Shelbourne
His time with the FAI proved short and fraught. Ireland went eight games without a win under Kenny, and Duff departed his post less than six months after joining the national setup. No official explanation followed, though it is understood he was unhappy with an investigation into a video shown to players before a friendly against England at Wembley in November 2020.
If that episode left a sour taste, Shelbourne offered a fresh start and, quickly, a platform. In November 2021 he stepped into his first managerial role when the club promoted him from their Under-17s as they returned to the Premier Division. Results turned almost immediately.
Shelbourne reached the FAI Cup final in 2022. A year later, a fourth-place finish hauled the Reds back into European competition for the first time in 18 years. The momentum built, and in 2024 Duff delivered the club’s first league title in 18 years, sealed with a dramatic final-day victory over Derry City.
The defence of that crown was far less smooth. By June of last year, Shelbourne sat sixth, 15 points behind leaders Shamrock Rovers, and Duff resigned with the Tolka Park side struggling to keep pace.
Now he steps into a different kind of challenge: an ambitious, data-driven Premier League club that has punched above its weight and wants to stay there.
For Brentford, this is another calculated move. For Duff, it is a return to the elite, armed with hard-earned lessons from Glasgow, Dublin and the international stage. The question now is simple: how far can this reunited partnership push the Bees?
